UNITED STATES PATENT OFFICE.

JAMES LOGAN GILMORE, OF SHARPSBURG, IOWA.

HOG-PEN.

SPECIFICATION forming part of Letters Patent No. 566,163, dated August 18, 1896.

Application filed March 28, 1896. Serial No. 585,228. (N0 model.)

To all whom it may concern:

Beitknown that I, JAMES LOGAN GILMORE,

a citizen of the United States, residing at Sharpsburg, in the county of Taylor and State of Iowa, have invented certain new and useful Improvements in Hog- Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pens or houses specially intended for sows; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of the house. Fig. 2 is a plan view of the same. Fig. 3is a plan view of the floor, and Fig. 4 is a vertical section taken on the line a: 00 in Fig. 2.

The house A is pyramidal in construction. Its sides a are of about the same area as its back a. The sides a converge toward the front I), which is made narrower than the back. This construction permits the sow to walk out easily.

B is a door hinged at its top to the front I) by hinges b and resting on the sides.

0 is a door which is hinged to the bottom of the door B and which hangs in a vertical position between the sides, leaving spaces 0' for ventilation. The top part of the house is provided with an opening O for ventilation.

In winter the sides and back of the house are covered with layers of straw D, secured in position by cross-pieces d or any equivalent retaining devices, such as wire-netting.

The bottom E of the house is formed of a substantially triangular frame 6, which fits loosely inside the house and is provided with one or more strengthening-pieces e.

E are floor-boards secured to the frame at short intervals apart to insure the drainage of the bedding, which is placed on the floor.

F is a chain which attaches the rear of the floor to the back of the house.

G are chains which attach the side portions of the floor to the sides of the house. The house, together with its occupants, can be moved from place to place, if desired.

Two chains 9 are attached to the lower part of the door 0 and engage with the sides of the house, so that the door 0 may be fastened; but any other approved fastening devices maybe used for securing the door 0 when desired to confine the sow in the house.

The peculiar pyramidal construction of the house prevents the sow from lying on or treading on her pigs, as the pigs always get into the rear corners and into the angles at the back and sides of the house.

The house can be used without the bottom, if desired. When the bottom is used, the chains G can be unfastened and the house tilted up whenever it is necessary to give the sow surgical treatment or for any other pur pose.

What I claim is- In a pyramidal pen or house, the combination, with two substantially triangular sides converging toward the front, of a substantially triangular inclined back, an inclined front portion narrower than the back, a door hinged to the bottom of the said front portion and opening outward, and a second door swinging inward and outward and hinged to the lower part of the first said door, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES LOGAN GILMORE.
